Abstract: _ 21 -MAINTENANCE OF STORED PROGRAM               CONTROLLED SWITCHING SYSTEMS          Abstract A time division, digital switching system capable of performing on-line testing of the actual communications paths that are switched is disclosed.  When an idle network time slot is found, a test vector register places a stimulus in the idle time slot and the stimulus is directed to the address of an idle port.  A loop-around path which includes a signature analysis chip (SAC) device is activated to divert a portion of the stimulus toward the SAC device.  The response of the SAC device is gated to a maintenance circuit which reads the generated signature.          Advantageously, the stimulus is selected to generate minimum noise at the addressed port so that if the user at the idle port picks up the telephone during the time slot used for testing, no loud noise wil be heard.

More particularly, the present invention relates to a novel allopolyploid yeast strain, Saccharomyces diastaticus NCYC 1460, which is the product of the spheroplast fusion of:       (a)  a hybrid, diploid strain of Sacch.diastaticus; and (b)  a fusion partner which is a polyploid brewing yeast strain of the species Saccharomyces uvarum (carlsber-gensis).            The fusion product of the present invention is capable of an en-hanced rate of fermentation and a generally higher degree of final attenuation than is typical of either of the fusion partners. Moreover the fusion product also evidences enhanced osmo- and thermo-tolerances and its multiple, non-allelic DEX gene comple-ment renders the organism well suited to the fermentation of sub-strates containing dextrins and oligosaccharides.

Abstract: Abstract of the Disclosure An artificial algal culturing reef unit, an artificial reef unit and an artificial culturing and fishing area unit, aimed at raising or culturing algae, fishes and shellfishes are usually submerged in a shallow sea zone with a depth ranging between 5 and 15 meters.  These units are required to be resistant to high waves and fast oceanic currents usually encountered in such sea zone.  Although concrete materials are suitable in consideration of its strength and costs, an alkali is necessarily emitted from their surfaces that is extremely harmful to diatoms and algae as well as fishes and shellfishes.  The present invention resides in an algal cul-turing reef unit and an artificial reef unit wherein a layer of iron sulfate or iron (II) sulfate or a layer of an acid and iron oxide powders are formed on the surface of concrete blocks for penetration into the inside of the blocks, whereby the alkali from the concrete is neutralized with an acid from the iron sulfate or iron (II) sulfate or an acid contained in said layer and iron oxides liked by algae or fishes and shellfishes are caused to exist in abundance on the reef surfaces.

Abstract: Abstract of the Disclosure Method of rock bolting by means of a continuous stranded cable, according to which method, a feed pipe (7) is shifted to a position facing a hole (24) drilled into a rock, a stranded cable (16) being fed through the said feed pipe into the drill hole, whereupon the feed pipe is pressed sealingly against the drill hole, a cementing agent is fed throug the feed pipe into the drill hole, and finally the feed pipe is displaced from the drill hole and the stranded cable is cut off. In order to seal the space between the stranded calbe and the feed pipe, a seal (20) provided between the cable and the feed pipe is compressed axially 50 as to con-strict the seal radially around the stranded cable (16) into contact with the circumferential surface of the stranded cable. In the rock bolting equipment intended for carrying out the method, the seal (20) between the stranded cable and the feed pipe is an elastically compressible sealing ring forming a passage hole which is constricted radially as the sealing ring is compressed axially. The equipment is provided with an operating mechanism for axial compressing said sealing ring.

L'enchevêtrement de disques mesure environ 2 .mu.m d'épaisseur. La préparation de ces surfaces sélectives s'effectue de la façon suivante. On fait subir à des plaques minces de nickel un traitement thermique initial par chauffage et oxydation dans un gaz oxydant durant un temps court à une température variant entre environ 1000.degree.C et 1100.degree.C. On réduit les plaques de nickel oxydées à une température d'environ 1100.degree.C en présence d'un gaz réducteur jusqu'à l'obtention de l'état métallique. On abaisse ensuite la température environnante entre environ 810 et 830.degree.C, et on fait circuler autour des plaques réduites à l'état métallique une atmosphère oxydante avec un débit suffisant pour chasser le gaz réducteur. On refroidit rapidement les plaques jusqu'à température ambiante et obtient les surfaces sélectives désirées.

Abstract: Abstract of the Disclosure An apparatus and method for measuring formation parameters by transmitting and receiving electromagnetic signals by antennas disposed in recesses in a tubular housing member and including apparatus for reducing the coupling of electrical noise into the system resulting from conducting elements located adjacent the recesses and housing.  More particularly, a method and apparatus employing electrostatic, but not magnetic, shielding of the low impedance  antenna  systems  and  inductive  signal  coupling  to enhance the signal at the receiver is disclosed.  This system is capable of measuring formation parameters in the presence of con-ducting bodies, e.g., the drill string, permitting incorporation of  the apparatus  in a measuring while drilling  (MWD)  logging system.  In a particular embodiment, high frequency electromagne-tic energy is used to measure formation resistivity.  Small low impedance coils are arranged in the wall or around the outer circumferential surface of a steel drill collar and spaced from the surface a minimum distance to allow efficient propagation and reception.  The low impedance receiver antennas are substantially electrostatically,  but  not magnetically,  shielded and  include inductive current coupling devices to further improve the signal. In a preferred embodiment, the coils are circularly configured about the collar and longitudinally spaced thereon to serve as transmitting and receiving elements which together with asso-ciated circuit components employ high frequency eletromagnetic wave  propagation  techniques  to  measure  formation parameters. The received signals are phase shifted and amplitude attenuated as they pass through the formation, and formation parameters are determined by detecting variations in travel time and attenuation between longitudinally spaced receivers.
